SrTEREOTYPE-PLAT HOLDER.

SPECIFICATION forming' part of Letters Patent No. 564,624, dated July 28, 1896.

Application filed April 9, 1896. Serial No. 586 ,799. (No model.)

To @ZZ whom, it may concern:

Be it known that I, CHRISTIAN C. KELLER, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Stereotype-Plate Holders and Adjustable Clamping Devices Therefor, of which the following is a specification.

My invention has relation to a holder for stereotype or similar plates, in which the same is adjustably secured in required firm position; and in such connection it relates particularly to the construction and arrangement of such a holder.

The principal objects of my invention are, first, to provide aholder for stereotype or similar plates of simple construction, by means of which the plates may be firmly held in required position and be adjusted with respect to the holder; second, to provide a plateholder consisting of a block in which are formed a series of grooves at right angles to each other, a series of clamps adjustable in said grooves and adapted to firmly clamp the plates to the face of the block, and, third, to provide in such a stereotype or similar plateholder a clamping device consisting of two members, one of which is adapted to slide in grooves of the holder, while the other is adapted to be fastened into the rst member and also to clamp the sides of the plate to the face of the holder.

My'invention, stated in general terms, consists of a stereotype-plate holder and adjustable clamping devices therefor constructed and arranged in substantially the manner hereinafter described and claimed.

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which- Figure l is a top or plan view of a stereotype-plate holder embodying the main features of my invention and illustrating two plates secured thereto. Fig. 2 is a side elevational view of Fig. l. Fig. 3 is a longitudinal section on the line a: of Fig. l. Fig. 4 is a top or plan view of broken sections of the holder from the under side adjacent to two channels of the same arranged at right angles to each other; and Fig. 5 is a perspective View of one of the clamping devices for securing a plate on said holder, partly in broken section as to one member of said device.

Referring to the drawings, d represents a block constituting the base or holder upon which stereotype or other similar plates A are adapted to be secured thereto. In the face of the block ce is formed aseries of grooves b and c, of rabbet form or inverted-T shape in crosssection. c are in two distinct series arranged at right angles to each other, which is the preferred form, although but one series, h or c, need be formed, unless, as in the case of large plates A, the four edgesof the plates are required for greater security to be clamped upon the block a.

' To enable the peculiarly-formed grooves to be more easily cut into the block a, I prefer, as illustrated, to form the block in two sections, of which the upper section a' constitutes the face of the block; but in use these sections must be firmly welded together or otherwise secured, so as to form in effect a single block. In the groove b or c is adapted to slide the lower member or base d of the clamping device. This member d is shaped in conformity with the groove, so that it may easily slide therein. The lower portion or wings d' of the member d is ridged or roughened,as at d2, and the under surface of the face d' of the block is correspondingly roughened or ridged, as at a2, as clearly illustrated in Figs. 2 and 3. The upper member of the clamp consists of a plate e, the under surface e of which is shaped complementally to the edges A of the stereotype-plate A. In the instance illustrated in the drawings these edges A' are beveled on two sides and at at A2 on the other two sides, and the under side e of the plate e is therefore complementally beveled as to two of the clamps and square as to the other two, so that they may engage the beveled surface on the opposite sides of the plate and abut snugly against the remaining unbeveled sides thereof. From the under surface of the plate e depends one or more legs e2, adapted to t into complementally-formed recesses cl3 in the upper member d, whereby as so arranged said clamps may be readily brought into engagement with a plate mount- In the drawings these grooves b and j IOO ed on the face of said channeled holder to lock the same securely thereon. The two members are secured together by means of a screw g, or other somewhat similar device, as clearly illustrated in Fig. 5 of the drawings. In operation the plate A is first mounted on the face of the block a in required position. The lower member CZ of each clamping device is then advanced in the groove b or c, or both, unt-il their upper members or plates e rest on the beveled side of the plate A on one side of the same and abut against the flat surface on the opposite side thereof. By turning the screw g the plates e will irmly clamp the plate A to the block and the lower members e will be firmly clamped against the under side ofthe face of the block.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

In combination with a block or holder for stereotype-plates having two series of grooves or channels in its upper face, arranged atV right angles to each other and substantially 1 -shaped in cross-section, 'ofa clamping device consisting of a base of a cross-section complemental to the grooves and adapted to be slid therein, an upper member arranged above the surface of the block and having a beveled edge, means uniting the upper member to the base, said baseiand upper member being complementally tongued and grooved,

a series of ridges formed on the upper sur'
